Description
This function tests whether
X
is a (positive) power of an indeterminate.
If so, it returns
true
; otherwise it returns
false
. An error is
signalled if
X
is not a
RINGELEM
or if
RingOf(X)
is not a
polynomial ring.
Example
/**/ use QQ[x,y,z];
/**/ IsIndetPosPower(x);
true
/**/ IsIndetPosPower(x/x);
false
